Nate Begeman	551bf3f800	kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBC and SUBE nodes that actually expose what's going on and allow for significant simplifications in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26255 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-17 05:43:56 +00:00
Nate Begeman	368e18d56a	Rework the SelectionDAG-based implementations of SimplifyDemandedBits and ComputeMaskedBits to match the new improved versions in instcombine.

Chris Lattner	c70cc35ddf	Fix typo that caused build failures for things trying to use m_Or. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26153 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-13 23:06:39 +00:00
Jim Laskey	f198eb9c62	Sync up the tag numbers with gcc4. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26146 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-13 16:56:43 +00:00
Jim Laskey	d96185aa62	Rename to better reflect usage (current and planned.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26145 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-13 12:50:39 +00:00
Chris Lattner	6a5b6d7633	Add a method git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26141 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-13 08:54:46 +00:00
Jim Laskey	ce72b1755f	Reorg for integration with gcc4. Old style debug info will not be passed though to SelIDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26115 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-11 01:01:30 +00:00

Evan Cheng	fae9f1cb34	Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gcc problem where it inline the map insertion call too aggressively. Before this change it was producing a frame size of 24k for Select_store(), now it's down to 10k (by calling this method rather than calling the map insertion operator). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26094 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-09 22:11:03 +00:00
Evan Cheng	6ae46c4c87	More changes to reduce frame size. Move all getTargetNode() out of SelectionDAG.h into SelectionDAG.cpp. This prevents them from being inlined. Change getTargetNode() so they return SDNode * instead of SDOperand to prevent copying. It should also help compilation speed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26083 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-09 07:15:23 +00:00
Chris Lattner	04a0f60b23	instead of keeping track of Constant/alignment pairs, actually compute the offset of each entry from the start of the constant pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26077 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-09 04:44:32 +00:00
Chris Lattner	69a9563969	Use a MachineConstantPoolEntry struct instead of a pair to hold constant pool entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26075 91177308-0d34-0410-b5e6-96231b3b80d8	2006-02-09 04:21:49 +00:00

Reid Spencer	0b118206bf	For PR411: This patch is an incremental step towards supporting a flat symbol table.

Andrew Lenharth	701f5ac73c	Random sampling (aka Arnold and Ryder) profiling. This is still preliminary, but it works on spec on x86 and alpha. The idea is to allow profiling passes to remember what profiling they inserted, then a random sampling framework is inserted which consists of duplicated basic blocks (without profiling), such that at each backedge in the program and entry into every function, the framework chooses whether to use the instrumented code or the instrumentation free code. The goal of such a framework is to make it reasonably cheap to do random sampling of very expensive profiling products (such as load-value profiling). The code is organized into 3 parts (2 passes) 1) a linked set of profiling passes, which implement an analysis group (linked, like alias analysis are). These insert profiling into the program, and remember what they inserted, so that at a later time they can be queried about any instruction. 2) a pass that handles inserting the random sampling framework. This also has options to control how random samples are choosen. Currently implemented are Global counters, register allocated global counters, and read cycle counter (see? there was a reason for it). The profiling passes are almost identical to the existing ones (block, function, and null profiling is supported right now), and they are valid passes without the sampling framework (hence the existing passes can be unified with the new ones, not done yet). Some things are a bit ugly still, but that should be fixed up soon enough. Other todo? making the counter values not "magic 2^16 -1" values, but dynamically choosable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24493 91177308-0d34-0410-b5e6-96231b3b80d8	2005-11-28 00:58:09 +00:00

Andrew Lenharth	aeef8fc5c6	Add support for a cycle counter intrinsic. As basically all processors have this and have it in about the same form, I think this makes sense. on X86, you do a RDTSC (64bit result, from any ring since the P5MMX) on Alpha, you do a RDCC on PPC, there is a sequence which may or may not work depending on how things are setup by the OS. Or something like that. Maybe someone who knows PPC can add support. Something about the time base register. on Sparc, you read %tick, which in some solaris versions (>=8) is readable by userspace on IA64 read ar.itc So I think the ulong is justified since all of those are 64bit. Support is slighly flaky on old chips (P5 and lower) and sometimes depends on OS (PPC, Sparc). But for modern OS/Hardware (aka this decade), we should be ok. I am still not sure what to do about lowering. I can either see a lower to 0, to gettimeofday (or the target os equivalent), or loudly complaining and refusing to continue. I am commiting an Alpha implementation. I will add the X86 implementation if I have to (I have use of it in the near future), but if someone who knows that backend (and the funky multi-register results) better wants to add it, it would take them a lot less time ;) TODO: better lowering and legalizing, and support more platforms git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24299 91177308-0d34-0410-b5e6-96231b3b80d8	2005-11-11 16:45:18 +00:00
Chris Lattner	d35f605613	Allow per-character control over what target assemblers allow in symbol names. This also changes the default to allow all of "$_." in addition to letters and numbers as symbol names. If you don't want this, use markCharUnacceptable to remove one of these or markCharAcceptable to add to the set.

Jeff Cohen	66c5fd6c53	When a function takes a variable number of pointer arguments, with a zero pointer marking the end of the list, the zero must be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23888 91177308-0d34-0410-b5e6-96231b3b80d8	2005-10-23 04:37:20 +00:00

Reid Spencer	0a262ba7c3	For PR616: These patches make threading optional in LLVM. The configuration scripts are now modified to accept a --disable-threads switch. If this is used, the Mutex class will be implemented with all functions as no-op. Furthermore, linking against libpthread will not be done. Finally, the ParallelJIT example needs libpthread so its makefile was changed to always add -lpthread to the link line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23003 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-24 10:07:20 +00:00
Chris Lattner	c44fff472c	Keep the killed/dead sets sorted, so that "KillsRegister" can do a quick binary search to test for membership. This speeds up LLC a bit more on KC++, e.g. on itanium from 16.6974s to 14.8272s, PPC from 11.4926s to 10.7089s and X86 from 10.8128s to 9.7943s, with no difference in generated code (like all of the RA patches). With these changes, isel is the slowest pass for PPC/X86, but linscan+live intervals is still > 50% of the compile time for itanium. More work could be done, but this is the last for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22993 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-24 00:09:02 +00:00
Chris Lattner	e0cbf970ac	Change live variables from using multimaps to using maps of vectors and rearrange some of the accessors to be more efficient. This makes it much more efficient to iterate over all of the things with the same value. This speeds up liveintervals analysis from 8.63s to 3.79s with a release build of llc on kc++ with -march=ia64. This also speeds up live var from 1.66s -> 0.87s as well, reducing total llc time from 20.1s->15.2s. This also speeds up other targets slightly, e.g. llc time on X86 from 16.84 -> 16.45s, and PPC from 17.64->17.03s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22990 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-23 23:40:41 +00:00

Chris Lattner	d5d0f9bd20	Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef) used to tack a register number onto the node. Instead of doing this, make a new node, RegisterSDNode, which is a leaf containing a register number. These three operations just become normal DAG nodes now, instead of requiring special handling. Note that with this change, it is no longer correct to make illegal CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this is bad, so don't do it. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22806 91177308-0d34-0410-b5e6-96231b3b80d8	2005-08-16 21:55:35 +00:00

Andrew Lenharth	6a9746127a	Like constants, globals on some platforms are GOT relative. This means they have to be allocated near the GOT, which new doesn't do. So break out the allocate into a new function. Also move GOT index handling into JITResolver. This lets it update the mapping when a Lazy function is JITed. It doesn't managed the table, just the mapping. Note that this is still non-ideal, as any function that takes a function address should also take a GOT index, but that is a lot of changes. The relocation resolve process updates any GOT entry it sees is out of date. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22537 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-28 12:44:13 +00:00

Reid Spencer	a0f5bf306c	For: memory operations -> stores This is the first incremental patch to implement this feature. It adds no functionality to LLVM but setup up the information needed from targets in order to implement the optimization correctly. Each target needs to specify the maximum number of store operations for conversion of the llvm.memset, llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations. The limit needs to be chosen at the threshold of performance for such an optimization (generally smallish). The target also needs to specify whether the target can support unaligned stores for multi-byte store operations. This helps ensure the optimization doesn't generate code that will trap on an alignment errors. More patches to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22468 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-19 04:52:44 +00:00

Reid Spencer	ee448630bd	For PR540: This patch completes the changes for making lli thread-safe. Here's the list of changes: * The Support/ThreadSupport* files were removed and replaced with the MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard. The implementation of MutexGuard.h is now based on sys::Mutex which hides its implementation and makes it unnecessary to have the -NoSupport.h and -PThreads.h versions of ThreadSupport. * All places in ExecutionEngine that previously referred to "Mutex" now refer to sys::Mutex * All places in ExecutionEngine that previously referred to "MutexLocker" now refer to MutexGuard (this is frivolous but I believe the technically correct name for such a class is "Guard" not a "Locker"). These changes passed all of llvm-test. All we need now are some test cases that actually use multiple threads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22404 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-12 15:51:55 +00:00

Reid Spencer	a229c5cce7	Final Changes For PR495: This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22354 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-08 03:08:58 +00:00

Reid Spencer	c7f083297c	For PR495: Change interface to Path class: readable -> canRead writable -> canWrite executable -> canExecute More (incremental) changes coming to close 495. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22345 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-07 18:21:42 +00:00
Chris Lattner	e578ab938b	Add support for building/representing the symbol table, add some enum constants git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22342 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-07 07:00:37 +00:00
Chris Lattner	e64e72b794	Make several cleanups to Andrews varargs change: 1. Pass Value*'s into lowering methods so that the proper pointers can be added to load/stores from the valist 2. Intrinsics that return void should only return a token chain, not a token chain/retval pair. 3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22338 91177308-0d34-0410-b5e6-96231b3b80d8	2005-07-05 19:57:53 +00:00

Chris Lattner	320181576e	iniital checkin of ELFWriter header. For now, the elf writer is only capable of emitting an empty elf file, with a section table and a section table string table. This will be enhanced in the future :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22290 91177308-0d34-0410-b5e6-96231b3b80d8	2005-06-27 06:28:45 +00:00

Andrew Lenharth	14f1703ae3	make AliasAnalysis know that VAArg writes memory. This is extremely conservative and should be fixed git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22267 91177308-0d34-0410-b5e6-96231b3b80d8	2005-06-20 15:24:23 +00:00
